Sustainability
Sustainability at Marnco
As we’ve grown, we’ve taken our footprint seriously. Since 2022, we’ve measured and offset our Scope 1 and 2 emissions and are expanding our focus to Scope 3. In 2023, we released our first ESG report—a step toward measuring impact, not just volume. By championing low-impact products and responsible land use, we’re helping protect soil health, support rural communities, and ensure a stronger future for farming.
